WR426 Flywheel Weight

I'm wondering if anyone on the forum has tried extra flywheel weight on the 426/450 and if so what the results were.

Making the kit was quite a feat. They must have thought it provided something. It'd be interesting to know if Zipty used one when competing on the WR.

my impression: did not change the personality of the motor overall but made a dramatic improvement at stall rpms/stall situations.

200 watts is a lot! does the kit have both a stator rewind and a high energy flywheel? do you have a part number for the kit?
I'm pretty sure they don't make it any more, but it's a Baja Designs external stator designed for the the YZ400/426. You just bolt a magnetic rotor to the flywheel with a extended bolt, this is 11 ounces so it should be similar to your flywheel weight. Then you have a new oversized billet aluminum cover that replaces the original case cover and you also have to replace the shift lever with one bent specifically for this kit. It has two 90 watt leads, so I guess it's (only!) 180 watts. I've had it in my garage for about a year so I guess it's time to hook it up.
